super-detype

library2.2.2jsnpmunverified

Super-detype is a CLI tool (v2.2.2) that converts an entire TypeScript project to JavaScript by stripping type annotations and compiling with Babel. It handles Node.js, React, Next.js, Remix, and Vite projects, but not Vue or Svelte. Unlike file-by-file converters or copy-paste tools, it processes whole directories at once. It requires Node >=22 and is primarily used via npx or global install. Release cadence is sporadic. Ships bundled TypeScript types for its own API but the tool itself generates JS.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import superDetype from 'super-detype'

✗ const superDetype = require('super-detype')

Package is ESM-only since v2.0.0. Use import syntax.

convertProject

✓ import { convertProject } from 'super-detype'

✗ import convertProject from 'super-detype'

convertProject is a named export. Default export is the main convert function.

CLI

✓ npx super-detype <input> <output>

✗ super-detype <input> <output>

Without global install, use npx. With global install, the CLI command is 'super-detype'.

Converts an entire TypeScript project at the given input path to a JavaScript project at the output path.

npx super-detype "/path/to/typescript-project" "/path/to/output"
